Coloring book in Flash tutorial


i am leaning Flash for about 3 weeks now, and i am quite good in that. I am AMAZED by all cool effects and trying to learn atleast 1 new every day.

This tutorial, Coloring Book in Flash , is giving me headache for the last 2 hours.

On the beggining of tut, it say to download and open souce FLA file- I saw that there is only drawing in start FLA file, so I make my own. Is that mistake, right at the beginning? If so, where I can find tut in the whole, so I can use my own images?

If there is/are someone who knows to help me about this tut, I will write more details.
